Palu – At least 2,443 of 20,000 workers in Palu, Central Sulawesi, are still not registered with state-owned worker insurance firm PT Jamsostek, according to data from the city's manpower agency.

Under a 1992 law, all companies employing more than 10 people for more than a year are required to insure them with Jamsostek. The law threatens violators with fines and punitive measures.

But despite the requirement, the Palu administration has refrained from taking firm action against violators of the law.

"We have always reminded companies that haven't insured their workers with Jamsostek about doing it," said Maswati, from the local manpower office.
